Jakkrasin Atsavatanachai (Thai: จักราสินธุ์ อัศวธนะชัย; born 3 November 1997), nicknamed Inn (อิน), is a Thai actor. In barely a year on screen he has gone from a supporting part in a family revenge drama to a prince of Ayutthaya and, in The Edge of Horizon (2026), the BL lead Phopthee Mankhongphak opposite Theethuch Khummuang, known as Ongsa.

He graduated from the International Program in Business English Communication at the Faculty of Liberal Arts, Thammasat University. His acting debut came in 2025 with the One31 series The Wicked Game, which aired from 27 September to 29 November 2025. The drama follows Peem, the youngest heir of the Yossinpaisarn family, who returns to confront the family that abandoned him and expose his father, Thanet; Inn plays the supporting role of Phakphum. With the cast he attended the series’ first premiere at Siam Pavalai Royal Grand Theatre on 24 September, an episode six fan screening at SF World Cinema, CentralWorld, on 1 November and the final episode fan meeting at MCC Hall on 29 November.

In 2026 he took a main role as Prince Ekathotsarot in The Last Duel, a historical drama inspired by events of the Ayutthaya period, which opened with an exclusive first episode screening at SF World Cinema on 11 March and closed with a final episode fan screening at Siam Pavalai on 22 April. The ten episode cast also includes Naphat Siangsomboon as the Maha Uparaja, Porapat Srikajorndecha as Nares, Chatchai Plengpanich as Bayinnaung and Chartayodom Hiranyasthiti as Nanda Bayin.

His first boys’ love lead followed in The Edge of Horizon (Arun Rung), The One Enterprise’s eleven episode historical drama set against the upheaval of 1932 Siam, which ran on One31 from 20 June to 29 August 2026. Inn plays Phopthee, the son of the palace wet nurse, a commoner with nothing but his pride and dignity, who grew up inseparable from the young Prince Thinnakon until rank and tradition pulled them apart. Years later, in a kingdom on the edge of change, the two meet again. Kathaleeya McIntosh plays his mother, and Chartayodom Hiranyasthiti, who was also in The Last Duel, plays Thinnakon’s father, Prince Vasin. Inn sings the duet “I Love You So Much” (รักเธอเหลือเกิน) with Ongsa for the soundtrack, and he attended the series’ blessing ceremony at GMM Grammy Place on 18 June and its world premiere at Major Cineplex Ratchayothin on 21 June 2026. His next announced project is Anantasaya: Our Love Stories.
